Occasionally the U.S. Department of State calls on the experts at PIDP to conduct international missions to monitor elections in the Pacific Islands. Working collaborately with the host countries' election officials and other international observer teams, PIDP puts together a group of regional experts who can both observe and learn from the experience. These missions are designed to not only observe the conduct of election officials and voters, but as a means to learn about the challenges and success stories in emerging democracies.
To date PIDP has lead election observation missions to the following countries:
- Papua New Guinea 2012
- Timor Leste 2012
- Solomon Islands 2010
- Autonomous Region of Bougainville (PNG) 2010
- Chuuk State, Federated States of Micronesia 2009
The director of PIDP was also included in the U.S.'s observer mission to Fiji in 2014.
